:SPECIFICATION forming part of Letters Patent No. 331,734, dated December 1, 1885.

Application led September 1, 1885. Serial No. 175,877. (No model.)

To all whom, it may concern:

Be it known that I, JOHN H. ROOK, a citizen of the United States, residing at Jonesborough, in the county of Grant and State of Indiana, have invented certain new and useful Improvements in Pumps; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it 1o appertains to make and use the same.

My invention relates to improvements in pumps, and it is designed to produce a noncorrosive cylinder for the reception of the plunger, and also a means whereby the same x5 may be connected to the pumpstock and to the pipe extending into the well or reservoir.

In the following description reference is had to the annexed drawings, in which Figure l represents a vertical section of the de- 2o vice; Fig. 2, a plan view of the reducer; and Fig. 3, a cross-section through the pump-stock, showing the clamp.

Adesignates acylinder, preferably of metal, with an internallyscrewthreaded shoulder,

B, at the lower end, and reduced at the upper end, forming an annular' shoulder, O. An exteriorly-tapering continuation, D, is formed on the top of said cylinder, as shown.

Within the cylinder A is secured a glass 3o cylinder, E, having on its upper end an annular exterior flange, F, which rests against and under the shoulder O, thus aiding in keeping the two cylinders in proper relation one to the other. Between the walls of the two cylinders is interposed the cement G, which iirinly secures the glass cylinderin place, lugs or iianges H being provided on the interior surface of the cylinder A to prevent all danger ofthe cement slipping. W'ithin the glass 4o cylinder operates the plunger I, which may be of any approved construction. The bore in the pump-stock K flares at the bottom, as shown at L, and receives the continuation D. Surrounding the pump-stock is a clamp con- 5 sisting ol' two parts or frames, M, secured together at the coincident projecting ends N by bolts or keys O. The shape of the clamp conforms to the shape of the stock or pipe. A similar clamp, P, encircles the pipe R below the cylinder, and each clamp is provided 5o with eyes S, one on each side being sufficient.

On the cylinder A, near both top and bottom, are eyes T. Through the eyes S and T pass the securing-bolts U, one end of each of which may be slotted to receive a wedge, as shown. The shoulder B receives a reducer,

V, internally ,tapering and screw -threaded externally, and provided with an outwardly projecting annular iiange, XV, which has recesses X for the reception of a wrench. Iith- 6o in the reducer tits the tapering end of the pipe R, which is surmounted by a valve, Y.

It is clearly evident that as the bolts U are drawn up they will force the tapers on the cylinder, pipe, and stock in close conjunc- 65 tion, making a tight and secure joint and keeping the parts of the pump in line. The use of glass for the cylinder in which the plunger operates absolutely prevents wear on the packing of said plunger, and hence obviates 7o all danger of leakage or inefective operation. The cement is of sufficient thickness to join the outer and inner cylinders, the outer one being large enough to allow for the taper-j oints and the clamps.

l. Combined with a pumpstock having its lower end provided with an interior taper, a plunger-cylinder having an integral reduced continuation provided with an exterior taper, 8c and having its interior diameter about the same as that of the said cylinder and pumpstock, substantially as specified.

2. Combined with a cylinder having an integral reduced externally-tapered continua- 85 tion, a glass cylinder interior thereto aud provided with an annular iiange resting under said reduced portion, a removable ring fitting one end of said exterior cylinder and provided with an internal taper, a pump-stock with the 9o lower end internally tapered, a pipe with an end externally tapered, and clamps holding the parts in conjunction, substantially as specified.

3. A pump having a plunger-cylinder, with 9 5 an externally-tapering reduced continuation at one end and at the other an internally-tw pering removable reducing-ring, combined with a stock having an internal taper at its of frames surrounding the stock and the pipe lower end, a pipe with an exterior taper at and secured to the eyes on the cylinder by one end7 and clamps for securing the cylinder, bolts, substantially as and for the purpose stock, and pipe, substantially as and for the speoiied. I 5 purpose specified. In testimony whereof I afx my signature in 4.
